This file can be retrieved through IEC103 protocol for fault analysisĬharacter format of IEC 101 uses 1 start bit, 1 stop bit, 1 parity bit & 8 data bits. Schemes for transfer of files-Example:IED's will store disturbance recorder file in the memory, When electrical disturbance is occurred in the field.
Cyclic & Spontaneous data updating schemes are provided.Possibility of classifying the data into different groups (1-16) to get the data according to the group by issuing specific group interrogation commands from the master & obtaining data under all the groups by issuing a general interrogation.Facility to classify the data into high priority (class-1) and low priority (class-2) and transfer the same using separate mechanisms.Data is classified into different information objects and each information object is provided with a specific address.Link address and ASDU (Application Service Data Unit) addresses are provided for classifying the end station and different segments under the same.Supports unbalanced (only master initiated message) & balanced (can be master/slave initiated) modes of data transfer.IEC TS 6 Security extensions to IEC 61 and IEC 64 protocols (applying IEC 62351).IEC 6 Guidelines for conformance testing for the IEC 60870-5 companion standards.IEC 6 Definition and Coding of Information Elements.IEC 6 General Structure of Application Data.Five documents specify the base IEC 60870-5: The IEC Technical Committee 57 (Working Group 03) have developed a protocol standard for telecontrol, teleprotection, and associated telecommunications for electric power systems. Part 5 provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems. IEC 60870 part 5 is one of the IEC 60870 set of standards which define systems used for telecontrol (supervisory control and data acquisition) in electrical engineering and power system automation applications.
